Usually, the Freedom to Operate (FTO) search or a clearance search is performed to identify the companies or the organizations and their respective patents which can obstruct the commercialization of the patent in question in the geography of interest. If there are any obstructing patents, the company can negotiate or in-license the overlapping patented technology before launching the product to avoid infringement later. In general, this type of search is conducted before launching a product in the geographical area of interest to ensure that the launched product does not infringe any patented technology later. The best results from the freedom to operate search will be granted patent overlapping with the technology of interest. For example, if a company wants to release a product in USA, the FTO search done will look for patents/patent applications in USA. A FTO Search is a search among the claims of in-force patents/patent applications for specific elements/steps of a product/process. A comparison is done between elements/steps of a product/process and individual claims of identified in-force patents/patent applications to determine the freedom to operate.
